I have recently started testing booting U-Boot from SPI on my gru-kevin (as opposed to chainloading it from vendor coreboot + depthcharge) and brought it to a better working state based on an initial support patch from Marty [1][2] and some follow-up work by Simon [3].
I tried to keep them as the git author when I took things from their work, but squashing other changes into those and rewriting commit messages makes things a bit weird in my opinion, especially for keeping their signoff. Do tell me if there is a better way to that.
As the Kevin and Bob boards are very similar. I assumed the config and devicetree changes will be appropriate for Bob as well, and applied them to it first. I do not have a Bob, so could not test on one myself, but Simon did test an earlier version of this and it appears to work [4].
Other useful things for these boards:
- Patch to fix a hang when usb controllers exit [5]
- Series to support HS400ES mode as HS400 training fails [6]
- Hack to skip eMMC reinitialization so it keeps working [7]
Is there docs updates to be done in doc/chromium/ for this so people know how to use it ?
This is for bare-metal use though, so it isn't anything to do with Chromium at present.
So are there docs for how do this? I didn't manage to find any, although the docs I find can be a little over the place in U-Boot so they may be there and I missed them, so either way docs would be fab.
